Senior Supt. Poklay said Tabulo admitted that he stole the fragmentation grenade and the grenade launcher in a naval base where he worked as plumber and asked Santos to help him to look for a buyer of the explosive he wanted to sell for P2,000.

When they failed to sell the explosives, they resorted into selling drugs that resulted in their arrest during a buy-bust operation at 9:51 p.m. on Rosario St., Gen. T. De Leon.

Police later discovered that the suspects were involved in robbery-holdup in Caloocan City while Santos had separate pending cases for frustrated homicide.
